Configure strict testing via phpunit.xml.

coverage-html can also be specified in the xml file. 

```
    <logging>                                                                                                            
        <log type="coverage-html" target="coverage"/>                                                              
    </logging> 
```
That being said, I know in the past I've been a huge proponent of the `coverage-html`, however its not needed for the automated builds and can easily be specified at command line when needed. My vote is to remove it.
